"I sang a song for Marc's birthday, for his 40th birthday, called 'My Man,' which is an old Barbra Streisand song from 'Funny Girl,'" Jennifer told Maria. "When I sang it, you know, she's so my idol. I was [like], 'I cannot believe I am trying to sing a Barbra Streisand song, this is insane! What are you thinking?!' But I sang and it was almost like I had graduated, you know what I mean? But I needed to get to that point.

"I sang and he was like, you know the tears in his eyes," Jennifer continued. "And we were both like, 'What was that?' I was like, finally, I am a singer. This is what I do. I don't ever have to doubt that in my mind, nobody can ever make me doubt it again."

But nowadays, Jennifer's confidence has never been higher as she puts the final touches on her upcoming album, "Love?" with producer Kuk Harrell, who is currently nominated for three Grammys and a Golden Globe.

Jennifer plans to tour her new album, still bringing it on stage, but keeping twins Max and Emme her top priority.

They are going to have to go with me," Jennifer told Maria of bringing the tots on tour. "Sometimes we have them in studio, sometimes I'm just like, 'Let me go in really quick and get back home really quick, but it's always with them in mind.

"For anybody who has children, you know, your priorities change as a mom," Jennifer continued. "You just have to… always work everything around their happiness… and their well being."
